These incredible pictures show British wing-walkers performing spectacular stunts at 150mph - over KUWAIT. The brave girls were exposed to extreme conditions as they were flown through the air at daunting heights performing the daring aerobatics. They were flown on a classic duo of 1930 Boeing Stearman biplanes which performed their own manoeuvres including loops, rolls stall turns and even inverted flights. The breath-taking display over Kuwait required the close coordination of the aircraft pilots and wing-walkers, along with a well-rehearsed routine and close formation flypast.
